Collars '30 are secured to theends of the outer tubes 9 and 10, adjacent the boxes 4 and 5, and aresecured to said tubes 9- and 10 by means of screws 31, or in any othersuitableor convenient manner. Thumb screws 32 are mountedin the collars30, and engage the inner tubes 11 and 12, this construction providingfor the adjustment of the distance between the camera and point 3. Thisadjustment is accomplished by loosening the thumbscrews 23, 24, and 32,and sliding the outer tubes 9 and 10 on the inner tubes 11 and 12,either toward or away from the point 3, until the desired'radius isattained, when by tightening the thumbscrews 23, 24. and 32, thedistance will be maintained. 7

Obviously, to attempt to roll the camera stand while the wheels 6 areresting on the plate-f8, would result in having to move the drivingmechanism connected to. the rod 29,.

and this, although of course not impossible, is thoroughly impractical.

I avoid this by providing two'jacks 33 and 34, which are secured to thecamera stand.

equipped with casters 36, of the usual ty of constructiomwhereby themoving of t e handles 37 operates to bring the casters 36 down upon theplate 8, andto-elevate the camera stand, and therewith the boxes 4 and5. so that the wheels 6 no longer contact the face of the plate 8. Inthis position, it is apparent the stand can be conveniently and easilymoved, as desired. When the requisite adjustment as to position has beenmade, the handles 37 are, lifted to the position shown in Fig. 1 (and indotted lines in Fig. 4), which lowers the wheels 6 to rest uponthe'plate "8, and elevates the casters 36 out of contact therewith. Inthis manner I insure very convenient and easy adjustment of the camera.regardless of its size and weight.

These jacks 33 and 34 are obviously designed-to be used'only whenreturning the camera to its original position after an exposure has beenmade, or when the standis to be moved backward or forward in changingthe distance of the camera from the point 3. Having described myinvention, what I regard as new, and desire to obtain by Letters Patentof the'United States, is: I
